Improved apparatus for carburetting air or gas



initrd Stairs @sind @Mina IMPROVED APPARATUS FOR CAIRB'URETTING- AIR ORGAS.

The Schedule referred to in these Letters Patent `a'nd making part; ofthe same.

To `all whom t ma/y concern:

Be it known that I, J osrAH Jonson, of Toledo, in the county of Lucas,and State of Ohio, have invented a new and improved Gas-Generator and Ido hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the accompanying drawings, makinga part of thisspecification, in which my invention is represented by a vertical axialsection.

The object of this invention is to provide, for public use, a cheap,convenient, and substantial carburetter, the action of which can be soadjustedyand controlled as to present a greater or less carburettingsurface to the air, whereby the latter can be combined with any requiredproportion of inflammable vapor, without changing the draught orquantity of air.

In the drawings- A represents the carbnretting-vessel, which is dividedby horizontal partitions, a* a2 a3, into four or more chambers, A1 A2 A3A4, and is surmounted by a gasometer, G, the top of which `may be helddown by a spring g, and the space between which and the upper edges ofthe vessel A may be packed and sealed in any suitable manner.

B is the cock, through which the gasoline or other -carburettingmatcrialis introduced.

C is the pipe, through which the supply of fresh air is introduced, saidair first passing through a heater, H, and then down, and in through thewall, under the partition a2, so as to be discharged into the chamberA3, in contact with the surface of the gasoline in the chamber.

D represents the exit-pipe, through which thecarburetted air isdischarged from the'gasoline-chambers into the gasometer, said pipebeing connected with said chambers by means of branches, Dl D2 D3, eachof which has a stop-cock, dl d2 da.

Each of the partitions acl a2 is provided with a tube, e e1 c2,extending downward from it, said tube being closed at its lower end, bya oat-valve, e.

The two chambers AdA3 are ea'ch provided with a waste-pipe, i? is, bywhich the gasoline, whenl arrivingl at acertain height, will ow into thechamber next below.

S is a sponge, designed to take up the gasoline by capillary attraction,and promote its vaporzation.

The partition a? is provided with one or more openings, m. y

O is the delivery-pipe, which connects both with the i gasometer and thechamber A4, by means of branches,

Ol 02, so that, by turning a stop-cock, ol or o2, the gas may be drawnfor use, either from the former chamber or from the latter. v Theoperation of the apparatus is as follows: The gasoline is introducedthrough cock B, and,

running down through tube c2, it fills chamber A3 to the height of tubei3, when it runs down into the next chamber A, lling that to the heightof tube i?, when it passes to the lower chamber, A1, filling that tillthe float-valve stops it from entering.

Or, the float-valves maybe so arranged'that the gasoline will passfreely through all the pipes, e e e2, to the lower` chamber, which itwill ll, until it raises the valve, and cuts o'ii the passage into thatchamber, when it will ll the chamber above, until, in turn, it closesthe Valve there,` after which it will, in like manner, fill chamberA3,'till it cuts oi the supply, when, after thus filling the lowerchambers, it will rise in chamber A, to any height required.

The latter is the preferable construction, since, by its means, thesupply can be better adjusted, and the upper chamber A4 can be made toact as a reservoir, to automatically fill the three lower chambers asfast as the duid within them wastes away.

If the two lower stop-cocks, dl d2, are closed, and

the upper -one opened, the air introduced through pipe O will passacross over the gasoline in chamber A3, and, taking up but little of thevapor, will escape directly through cock d3, filling the gasometer andchamber Awith a gas of comparatively poor qual- If the middle cock, d,be opened, and the others closed, the air from pipe C will not only passover the same surface of fluid as before, but, going down through pipet3, into chamber A2, will pass over the fluid therein, and escapethrough cock d2, much richer than before.

And, likewise, if the lower cock, d, be opened, the two upper ones beingclosed, the air from pipe C will be obliged to travel over the gasolinein all threeof the chambers A3 A2 A, before it can escape through branchDl into the 'gasometen When gasoline is allowed to stand in chamber A,its evaporation also -will enrich the gas that has already passed overthrough pipe D.

If there should, in consequence of this, orwhen first lling theapparatus, be any diiference between the richness of ,the gas in chamberA4 and gasometer G, i t can be taken for use from either, or from bothof .said chambers at once, by means of two branches, O 02 and cocks olo2, so as to regulate the qualityfas may be desired.

The whole apparatus is simple in construction, cheap, economical inoperation, and not liable to get out of order, or cause accidents of anykind.

As will have been already clearly understood, from.

the above description, it will enable the operator, by

'properly adjusting the stop-cocks, to produce and draw off for use gasor carburetted air of any degree of richness of illuminating-qualitythat may be desirable.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of a series of chambers, A A A3, pipes e e1 e2, 2 3,valves fu v fv, supply-pipe O, and exit-pipes D D2 D3, having cookedl d2d3, in such a manner as to operate substantially as and for the purposesset forth.,

2. In connection with the several parts, thus arlranged and operating,the arrangement and ootnbination ofthe delivery-pipe O, having twobranches,
